Best offline inventory apps that work without internet (2026)
Ofisx Offline Inventory (listed on Google Play as "Inventory Management" by Ofisx) is a free inventory app for Android and iPhone that works 100% offline: no account and no internet are needed, and your stock, barcode sales, purchases and customer and supplier balances stay on your phone, backed up to Google Drive or iCloud. Below we compare it honestly with the other apps people use when the shop, warehouse or job site has no reliable connection.
Short answer: which one to pick
- Phone only, no sign-up, real offline: Ofisx Offline Inventory — data lives on the device, barcode scanning with the camera, customer and supplier balances, thermal printer receipts. Free up to 100 products and 300 transactions; Pro is a one-time lifetime purchase.
- A team that is online most of the time but sometimes loses signal: Sortly — a cloud app whose mobile apps have an offline mode that syncs when you reconnect.
- Indian business that needs GST invoices: Vyapar — offline-first billing and inventory for Android and Windows.
- You want to design your own fields: Memento Database — a general offline database app you can turn into an inventory list.
- A desktop file is enough: a spreadsheet (Excel or LibreOffice Calc) — free and offline, but no barcode sales flow or low-stock alerts.
- Several employees, a web panel and one shared stock: this is not an offline job — use a cloud app such as Ofisx Inventory Management (online).

The apps in detail
Ofisx Offline Inventory
Built for offline use from the start: there is no sign-up and nothing is sent to a server. You add products (or import them from Excel), scan barcodes with the camera, record sales, purchases and expenses, and see low-stock alerts, profit, VAT/tax and cash-flow reports.
It also keeps current accounts: who owes you, who you owe, collections, payments, due dates and customer or supplier statements. Receipts and invoices can be shared as PDF or printed on 58 mm / 80 mm thermal printers. 140+ currencies are supported.
Backup: manual backup to Google Drive or iCloud is free; Pro adds automatic daily backup and unlimited products and transactions.
Sortly
Sortly is a cloud inventory app with photos, folders, QR/barcode labels and multi-user access. According to its help center, offline mode is available in the mobile apps only and updates inventory levels on your device until you reconnect, then pushes changes to every device on the account.
Choose it when shared, multi-device inventory matters more than staying fully offline.
Vyapar
Vyapar is a billing, inventory and accounting app aimed at Indian retailers, wholesalers and service businesses. It is offline-first: invoices and stock entries can be made without a connection and update across devices when the connection is back.
Its strongest point is GST billing, so it fits best if you sell in India.
Memento Database
Memento is a general-purpose database app with 20+ field types including barcodes, so you can build an inventory, asset or serial-number log yourself.
It is flexible, but sales, purchases, receipts and customer balances are not ready-made — you design them.
Spreadsheet (Excel or LibreOffice Calc)
A stock sheet with one row per movement and a SUMIFS balance works offline and costs nothing. It does not scan barcodes at the counter, warn you about low stock or print receipts, and two copies of the file quickly drift apart.
inFlow On-Premise (discontinued)
inFlow On-Premise often appears in older "offline inventory software" lists. inFlow ended support on 31 July 2024 and no longer sells or activates new licenses; the company points users to its cloud version, which needs internet.
How to choose an offline inventory app
- Fully offline or "offline mode" — A fully offline app keeps the data on the device and never needs a server. An offline mode in a cloud app caches data and syncs later — fine for short outages, but you still need an account and a connection to start.
- Where the data lives and how it is backed up — With on-device data, backup is your job: check that the app can back up to Google Drive, iCloud or a file, and test a restore before you rely on it.
- Barcode scanning with the phone camera — Scanning at the counter is what makes a phone app faster than a notebook or spreadsheet.
- One device or a team — Offline apps are usually single-device. If several people must sell from the same stock at the same time, pick a cloud app.
- Free tier limits — Compare product and transaction limits, and whether you pay a subscription or once.
- Customer and supplier balances — Many small shops also sell on credit; an app that keeps stock and balances together saves a second notebook.
What Ofisx Offline Inventory does not do
- Ofisx Offline Inventory is single-device: there is no multi-user access and no web panel. If you need those, use the online Ofisx Inventory Management app instead.
- It does not issue e-invoices to government systems and has no marketplace or e-commerce integrations.
- The iPhone version is not available in every App Store country; the Android version is on Google Play worldwide.
Frequently asked questions
What is the best offline inventory app?
For a small shop that wants to track stock from one phone with no internet and no account, Ofisx Offline Inventory is a strong choice: it stores data on the device, scans barcodes, keeps customer and supplier balances and is free up to 100 products and 300 transactions. If your team is usually online and only needs to keep working during outages, Sortly's offline mode is an alternative; for GST billing in India, Vyapar.
Is there a free inventory app that works without internet?
Yes. Ofisx Offline Inventory includes every feature for free up to 100 products and 300 transactions, with free manual backup to Google Drive or iCloud; Pro (one-time purchase) removes the limits. Memento Database and LibreOffice Calc are also free options if you build the inventory yourself.
Can I scan barcodes offline?
Yes. Camera barcode scanning does not need a connection in Ofisx Offline Inventory; you can add products and sell by scanning with no internet.
What happens to my data if I lose my phone?
In an offline app the data is on the device, so keep a backup. Ofisx Offline Inventory backs up to Google Drive or iCloud (manual backup is free, automatic daily backup is in Pro) and you restore it on the new phone.
Can several employees use an offline inventory app?
Usually not at the same time on shared stock — offline apps keep data on one device. Ofisx Offline Inventory has no multi-user access; for a team, the cloud-based Ofisx Inventory Management app offers permission-based accounts and a web version.
Does Sortly work offline?
Partly. Sortly's Android and iOS apps have an offline mode that updates inventory on your device and syncs when you reconnect; the web app needs internet and you need a Sortly account.
Do I need to create an account?
Not for Ofisx Offline Inventory — install it and start adding products. Sortly requires an account.
